LOZENGE- MACHINE.

SPECIFICATION forming part of Letters Patent No. 363,681, dated May 24,1887.

Application filed June 6, 1885. Renewed October 18, 1886. Sel'ial No.216,589. (No model.)

To aZZ whom it may concern.-

Be it known that I, THOMAS Ronnarson, of the city of Toronto, in thecounty of York, in the Province of Ontario, Canada, manufacturer, haveinvented certain new and useful Improvementsin Lozenge-lliachines, ofwhich the following is a specification.

The invention relates to certain improvements upon a lozenge-machinefully described in specifications attached to United States patentsissued tome on J annary 4, December 26, 1876, and May 9, 1882, to whichspecifications I refer for any details of description not found in thefollowing specification, which will be directed merely to explain theimmediate improvements involved in my present invention, the object ofthe present improve ments being to insure greater accuracy intheprinting and embossing of the lozenges, and at the same time to impart ahigher and more complete finish to each lozenge; and it consists, moreparticularly, in arranging adevice by which each lozenge, after beingcut from the sheet of paste, is pressed into a mold, where it isembossed or printed and then deposited upon a traveling tray on whichthe lozenges are arranged in rows, ready to be placed in thedrying-room.

Figure 1 is a side elevation, showing the position of the mechanismbefore the cutters have been brought down upon the paste. Fig. 2 is asectional side view showing the mechanisniin the same position as inFig. 1. Fig. 3 is a side elevation showing the position of the mechanismwhen the cutters have been brought down upon the paste. Fig; 4 is asectional side view showing the mechanism arranged as in Fig. 3. Fig. 5is an en larged sectional side view of the molding-cylinder and itsconnections. Fig. 6 is a perspective detail of the moldingcylinder. Fig.7 is a perspective detail of the cam and its lever for operating theplunger-in the moldingcylinder. Figs. 8 and 9 are perspective de tails,partially in section, showing the means for lifting the fingers employedin drawing the lozenges out of the cutters. Fig. 10 is a perspectiveview of the machine.

-In the drawings all parts marked A represent the main or stationaryframe of the machine.

B represents the traveling apron, upon 'which the sheet of paste isconveyed to the cutters.

G is the cutterhead,which is attached to or forms part of the table D,which is hinged at a to the frame A. ThistableDextends across the fullwidth of the machine, the said width being regulated according to thenumber of cutters in the head 0.

E is the main driving-axle of the machine, and derives motion from anyprimary motor desired. All the moving parts of the ma chine are gearedto and derivemotion from the aXle E.

12 is a connecting-rod attached at its upper crank, Z), connected to theaxle F, which is geared to and derives motion from the main axle E, asindicated in Fig. 2.

c is abalance-weight connected to the end of the lever d, which ispivoted to the main frame A, and is connected by the rod 0 to the tableD, for the purpose of balancing the weight of the said table.

When the axle F revolves, the table D, being hinged at a,derives avertically-reciprocating movement which is designed to bring the cuttersagainst and away from the sheet of paste alternately, each downwardmovement of the cutter-head 0 being designed to cut out from the paste arow of lozenges. As the head ascends, the fingers f (see Figs. 8 and 9)draw from each cutter a lozenge. As these fingers are attached to theframe which operates the push-bars, as fully described in my Americanpatent issued on May 9, 1882, it is not necessary here to describe theconstruction and operation of the said push bars, it being merelynecessary to say that the fingers f draw the lozenges from the cuttersto a position where they may be reached by the push-bars, which operateand are constructed in the same manner as the push-bars described insaid patent, my present reason for referring to the fingers being merelyto explain how I- clear the fingersfrorn the lozenges after they havebeen drawn by the said fingers into range of the push-bars, which, asbefore stated, are operated as described in my former patent. Thefingers f, it will be noticed, are connected to a head, g, which ishinged at h to the pushbar frame 6. A cam finger or pawl, j, is securedon each side of the head g,and is slightly end to the'table D and at itsbottom end to a longer than the'distance from its pivot to the top ofthe ledge 70. When the fingers have reached the position in which theyare shown in Fig. 9, the lozenges have been drawn into 5 range of thefirst push-bar. At this point the finger or pawlj falls into a notch, Z,made in the ledge k, and as the head g commences to travel back towardthe cutter-head O the pivoted finger-j raises the said head on its hinge7b, lifting the fingers f clear of the lozenges,

and in the event of the said fingers lifting any of the lozenges, any solifted will be pushed down by coming in contact with the springplates m.WVhen the head 9 returns to obtain a fresh supply of lozenges,asindicated in Fig. 8, the pawl j falls into the slot m made in theplate'k, which slot is sufficiently large to allow the pawl j to swingon its pivot without raising the head g,- or, in other words, the pawl jswings freely on its pivot when over the slot m, so that on thereturnstroke of the head 9 the pawlj assumes the angle it is indicatedin in Fig. 9, so as to be in a position to act when the headretnrns. Therow of lozenges deposited within range of the push-bars are then drawnforward by the action of the said push-bars until they reach the end ofthe table D at which the molding-cylinder G is located. I term this amolding-cylinder, although strictly speaking it is not a cylinder, beingmerely four bars, a, running parallel with the axle 0, and supported byheads 1), which are fastened to the axle 0 Each of these bars a has aseries of holes, q, pierced in it, which enges to be molded, and are thesame distances apart as the cutters, so that each lozenge cut finds acorresponding hole in the particular bar a which happens to be at theend of the table D when the lozenges are drawn from the said table ontothe top of the bar a. Consequently, each lozenge so drawn is depositedinto one of the holes q.

O n reference to Figs. 2, 4, and 5 it will be noticed that each hole (1is provided with a plunger, r, which plungers are attached to a bar, 8,extending from one head to the other, and has friction'rollerstjournaled on each of its ends. The axle 0 is supported at each end 50by a bracket, H, which is suitably fastened to the main frame A. On theinside surface of each of these brackets a cam groove, to, is made so asto receive the friction-rollers t, and is shaped so as to operate theplungers 'r in the manner and for the purposes hereinafter described.

A carriage, I, is supported in suitable guides on the frame A. andextends across the machine. A corresponding carriage, J, is similarlysupported and is located on the opposite side of the cylinder G.

An arm, K, is pivoted on each side of the frame A, and its upper end isconnected to the carriage I by the link L.

An arm, M, is pivoted on each side of the frame A, and is connected tothe arm K by the holes represent the size and shape of the loz-- whichderives motion, as indicated in Figs. 2

and 4, from the main axle E.

Arow of plungers, R, are supported in suitable journals on the carriageI, and are designed so that each hole q shall have a plunger Itimmediately opposite to it when in a horizontal position. These plungersR are shaped so as to' fit the holes q, and havetheir ends plain orengraved, so that when they are brought into contact with the lozengeswithin the hole q a corresponding impression will be stamped upon thelozenges.

On the carriage J a series of circular cleaning-brushes, '0, arearranged so as to come opposite to the holes q, as indicated in Fig. 5.

It Will be noticed that there are four bars, a, set at right angles toeach other, so that when two are vertical the other two are horizontal,These bars are made to change places in the following manner: An arm, S,is pivoted loosely upon the axle 0. One end of this arm is connected bythe rod T to a crank attached to the axle U, which is geared to andderives motion from the main driving-axle, as indicated in Figs. 2 and4. The other end of the arm S is connected to the frame of the pushbars:12, which, as before explained, operate in the same manner as that inwhich they are described in the patent before referred to. The revolvingof the axle U imparts a reciprocating motion to the frame of thepush-bar x, and as I wish the molding-cylinder G to revolve, so as tooperate in connection with the reciprocating motion of the push-bars, Iplace a pawl, y, on the arm S and secure a disk, V, to the axle 0. inits periphery, which notches are four in number and at equal distancesapart corrcsponding with the four bars a of the moldingcylinder G. Ateach backward stroke of the arm S the pawl 1 is brought into contactwith one or other of the notches 2, so that at the forward stroke of thearm 3 the disk V is caused to make one-fourth of a revolution, therebybringing the bar a which was standing at the top of the cylinder down toits horizontal position opposite to the plungers R, each of the otherbars simultaneously being changed in their position. It thereforefollows that when the holes in the top bar a are filled with lozenges bythe action of the pushbar 00 the said bar a is brought opposite to theplunger R, which is then actuated by the mechanism hereinbeforedescribed, so as to press the lozenges into their respective holes andthereby finish them, as mentioned. By the time that the mechanismhereinbefore described is ready to move the molding'cylinder anotherquarter of a turn the plungers B have been withdrawn from theirrespective holes, and when the bar which has thus been filled reachesits bottom position the finished lozenges This disk V has notches z cuton the end of the lever 6.

' of course the opposite end is correspondingly are deposited upon thetray W. As the lozenges thus pressed into the holes would not fall outof their own accord,I form a movable gate, 2, inthe cam-groove a. Thisgate is exhibited in-Fig. 7, and it will be noticed is connected by therod 3 to the pivotedlever X, the opposite end of which is provided witha frictionroller resting upon a cam, Y, attached to the axle U. This camY is so shaped thatthe lever X istiltedjust at the moment that thefrictionroller 1 enters the gate 2, and consequently the plungersattached to the bar 8 provided with the particular roller entering thegate, as referred to, are forced down, so as to press out from the holesthe lozenges which had previously been pressed into them by the actionof the plungers described. The next time that the cylinder G is causedto revolve the plate a thus emptied of its lozenges is brought oppositeto the brushes c,which are forced into the holes simultaneously with theplungers R on the opposite side, whereby each hole is cleaned outpreparatory to being brought into the vertical position ready to receivethe next supply of lozenges. moved back, as hereinbefore described, itsend 4 eomesin contaetwiththe projection 5 formed This lever is pivotedat7 to some convenient point intheframe A. By coming in contact with theprojection 5 that end of the lever (i is pushed down, and

moved up,so as to bring the brushes 8,which are attached to the end ofthe levcr,against the plunger R,so as to thoroughly clean them. A

brush, 9, which extends across the machine at the point indicated,brushes off and cleans the ends of the plungers was they are carriedpast when moving with revolving cylinder G. By this arrangement thefaces of both plungers R and r are kept clean to insure their perfect Iin order to make the matter clearer I may mention that the said cam a isso shaped that the plungers 1', when the plate is in position to receivethe lozenges, are almost flush with the surface of the bar a, so thatwhen the lozenges are deposited in the holes they will each rest upontheir respective plunger. When the bar thus filled with lozenges isnioved from its first position to the horizontal position opposite tothe plungers R, the cam a is so shaped as to draw the plungers rinto theplate, thereby permitting the lozenges to reeedeinto the holes When thecarriage I is q. After the plungers B have entered the holes q andcompressed or molded the lozenges within them, the plate a, with thelozenges so a .onto the tray XV. After having so discharged the lozengesthe cam a is so shaped that the ends of the plungers 1' shall remainoutside of the plate it until they have passed the brush 9, after whichthey are retreated untilthey are clear of the plate a, so that thebrushes 1) pass entirely through the said plate when cleaning the holes.After this point the cam is shaped so as to bring the plungers 1' backinto their initial position.

There are two other points of importance that I have omitted to referto, the first one of which consists in placing astationary plate,13, insuch a position that the plungers a must pass close to the plate afterhaving discharged the lozenges fromthe plate a. This plate 13 isprovided for the purpose of knocking off any lozenges which may happento adhere to the plungers 2. By this plate thepositive delivery upon thetray IV of everylozenge is insured. I have not referred to any mechanismfor moving the tray \V, as the means for doing so is fully described inmy former patenls referred to in this specification. The second point ofimportance which I have not referred to before is a stop, 14, providedfor the purpose of arresting the motion of the cylinder G.

I This stop 1st is held in a suitable guide formed in the frame A, andis operated by a cam, 15, placed upon the axle 0. This cam is so shapedthat the stop ll is thrown out so as to extend below the plate a when itcomes opposite to the plungers R, and is withdrawn by the action of thecam in time to allow thenextmove ment of the cylinder. At each end ofthe carriage I a finger, 16, is fixed. The end of this finger extendsslightly beyond the plungers R, and is tapered, so that when thecarriage l. is thrown forward toward the bar a the tapered ends of thefingers enter holes made in the bar a, so as to hold the said barstationary in its exact position ready to receive the plungers R.

I am aware of the English PatentNo. 711 of 1857, in which the lozengesare cut in proximdistort the crackers, and does not deposit them intheir proper order on the tray. By arranging the stationary plate 13substantially under the axis of the cylinder the lozenges, should anyadhere to the plungers, are removed in perfect condition into theirproper place on the carrier.
